JDE1-Use Change Request (P5310) to manage job Variations

 Hello,

Has anyone implemented Change Management in JDE E1? 

We are planning to run a pilot to verify whether the use of Change Request (in its simplest way) is better that Work Order to manage approved variations on Jobs. Entries in AP,AR,GL or on Purchase Orders use the Subledger Type J and Subledger - the change request number, to record costs per variations

The error message 'Invalid Subledger 0000001 J' is displayed when using the Subledger Type J and Change Request No in Purchase Order detail line (P4310). Has anyone encountered this error before? 

Thanks, Linda
